As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under "Comments" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade.Please review our full return and shipping policy here.
Measure Twice, Cut Once
Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.
How to Use a Measuring Tape
Extend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.
Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2" has a bigger mark than 1/4" which has a bigger mark than 1/8". The smallest mark follows at 1/16". Please be aware that some measuring tapes may have even smaller increments.
Features of a Measuring Tape: Sliding End Hook
The sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).
Sanitizing Acrylic and Polycarbonate Sheet [X]
Acrylic and Polycarbonate Sneeze Guards and like products require special care while cleaning and disinfecting. To maintain the optical clarity of sneeze guards and other acrylic or polycarbonate items, use an acrylic or polycarbonate safe cleaner like Novus Plastic Polish #1, Brillianize Plastic Cleaner, or a mild soap solution.
Please reference the following compatible cleaners when DISINFECTING acrylic and polycarbonate items. The use of commonly available commercial alcohol or ammonia-based disinfectants may cause crazing and damage.
Homopolymer Polypropylene for Chemical Tanks & Fabricated Parts
Homopolymer Polypropylene sheet is a lightweight thermoplastic designed for fabricated components that require chemical and corrosion resistance, low water absorption, and greater stiffness than copolymer polypropylene.
A rugged, lightweight material with good wear resistance for many industrial applications, homopolymer polypropylene is highly resistant to many chemical solvents, bases, and acids. Its balance of rigidity, weldability, and ease of fabrication makes it a reliable choice for demanding chemical and structural environments.
Looking for improved impact resistance in cold environments? For low-temperature applications, take a look at Copolymer Polypropylene.
Why Choose Homopolymer Polypropylene?
This is a rigid, lightweight, and cost-effective material with dependable chemical resistance. It is the correct choice if you need:
Chemical Resistance:
Resists many acids, bases, solvents, and other industrial chemicals.
Low Water Absorption:
Absorbs very little water, supporting consistent performance in wet and humid environments.
Rigidity:
Provides greater stiffness and tensile strength than copolymer polypropylene for covers, panels, and tanks.
Weldability:
Can be welded and fabricated into tanks, containment equipment, trays, and other custom assemblies.
Homopolymer vs. Copolymer PP: Which Do You Need?
While both are polypropylene-based plastics, their properties lend themselves to different applications.
Choose Homopolymer (This Sheet) if standard stiffness, reliable tensile strength, and stability at moderately elevated temperatures are your priorities.
Choose Copolymer if you require enhanced impact resistance or if the material will be exposed to low-temperature environments.
Fabrication & Machining
This material provides strong mechanical properties that make it suitable for a wide variety of fabrication methods. While it is tough and flexible, proper machining speeds and feeds are required to prevent material melting and ensure clean cuts.

PRONE SH
Technical Performance
This thermoplastic polymer is engineered for applications requiring structural rigidity, reduced weight, and high resistance to chemical degradation.
Typical grades can maintain reliable strength and structural stiffness up to 180°F.
Rigidity:
Provides greater stiffness than copolymer polypropylene for fabricated panels, covers, tanks, and equipment components.
Key Properties
Moisture Resistance:
Highly resistant to water absorption, making it ideal for liquid containment and fluid handling systems.
Mechanical Stability:
Offers reliable mechanical properties in a tough, flexible, and lightweight format.
Fatigue Resistance:
Resistant to continuous fatigue, allowing it to act as a functional living hinge.
Electrical Insulation:
Standard unfilled polypropylene is electrically insulating.
Common Industrial Applications
Chemical Processing: Fabricated chemical tanks, plating tanks, secondary-containment components, and equipment covers.
Laboratory & Clean Environments: Lab trays, work surfaces, cabinetry, containment components, and fabricated equipment.
Water & Wastewater Equipment: Tank components, baffles, covers, and non-pressure fluid-handling assemblies.
Industrial Fabrication: Guards, panels, housings, spacers, trays, and other lightweight rigid components.
Engineering Limitations & Alternatives
While homopolymer polypropylene offers strong chemical resistance and rigidity, specific environments may require alternative materials:
Cold Environments: Homopolymer grades may become brittle when exposed to low-temperature conditions. Better Alternative: For high-impact needs at low temperatures, choose Copolymer Polypropylene.
Wear & Bearing Applications: Standard homopolymer polypropylene is not designed for heavily loaded bearings, gears, or continuous sliding-wear components. Better Alternative: For load-bearing wear parts such as bearings, gears, and rollers, consider Cast Nylon.
Extreme Heat Operations: While it performs well at moderately elevated temperatures, excessive continuous heat will soften the material. Better Alternative: When higher temperature capability and broad chemical resistance are required—and lower stiffness and greater creep are acceptable, consider PTFE.
